Serial No. 586,540.

- My invention relates to apparatus for lilling serrations, grooves, or other forms of receptacles in bearings with a lubricating Y graphite compound, relating ymore particuy and compact same therein; that will effect an even and like distribution of same to each and every groove or receptacle thereof; that will prevent any surplus compound remaining upon the bearing surface; that will be simple in operation and provide rapid and therefore economical production.

With'the above objects in view, I have illustrated in the accompanying drawings a preferred embodiment of the apparatus and its application, wherein- Figure 1 is a side elevation of the appa? ratus.

Figure 2 is an enlarged vertical side elevation of a portion of same, partly in section.

Figure 3 is an enlarged transverse sectional view through the apparatus, on the line III-III of Fig. 2.

Figure 4 is an enlarged elevation of a portion of the apparatus with parts, including a sleeve bearing, in section, to more clearly illustrate the method, and

Figure 5 is a transverse sectional view on the line V-V of Figure 4L, of the sleeve with the compacting member disposed therein.

The apparatus comprises in structure a frame including a support 1 mounted upon legs 2, constituting a table, and a vertically disposed housing 3 mounted upon said table.

rThe table top has depending therefrom the rods l carrying a plate 5 to which is secured an air cylinder 6 provided with ports 7 and 8,

respectively, and has slidably fitted therein a fiuid actuated piston 9 mounted on the rod 10 extending therethrough.

Alining with the fluid cylinder and secured to the table l is a cylindrical member or container 11 for confining the lubricating compound 12. The container has a piston 13 fitted therein upon the rod 10, for applying pressure to the compound and is provided at its upper end with a head or interchangeable self centering chuck 14 to engage the lower end of a sleeve 15, said chuck being open to the container and provided with an annular recess 14 as a chucking seat for the sleeve.

Directly above and alining with the container is a hollow member 16 slidably fitted for vertical movement upon the housing 3, said member having a head 17 at its lower en d and adapted as a companion chuck, to engage the upper end of the sleeve 15 and close its grooves l5.

lVithin the member 16 is arranged a worm wheel 18 fixed to a vertical shaft 19, said shaft having removably attached thereto a compacting member 2O adapted to move downwardly with the chuck head of the slidable member and enter the sleeve.

The compacting member is provided with one or more longitudinally disposed fluted of the flute being preferably rounded, presenting in cross section, a substantially dual cam form as shown in Fig. 5.

The compacting member is continuously rotated in practice, being accomplished by means of a worm 21 mounted transversely within the slidable member on a shaft 22 and in engagement with the worm, the rotary movement thereof, being provided by a motor 23 mounted upon a bracket 24 secured to thehousing, said motor being connected to the worm shaft by a suitable universal coupling mechanism 25 to permit the compacting member rotating regardless of the vertical movement or position of the slidable member 16.

CSI

To the upper portion of the housing is adjustably secured a slide 26, adjustment being accomplished by means of a threaded rod 27 extending through a lug 28 of the housing, and the nuts 29 and 30.

To the slide is secured a cylinder 31, in alinement with the member 16 and provided with ports 32 and 33, respectively, and having arranged therein a fluid actuated piston 34 the rod 35 of which is connected with the slidable member 16 at its head 36, said piston being adapted to actuate the member 16.

In practice, both of the cylinders 6 and 31 are to be connected, at their ports, to an air supply, and be provided with means for controlling each inde Dendently, the ports in each being employee alternately as intake and exhaust. y

In the drawings the sleeve 15 is shown as 'chucked between the heads 14 and 17 vready to have the grooves 15 thereof filled with the lubricating compound, but the method of operation will be setforth as beginning with the chucking of a sleeve.

Operation Assume that the piston 34 within the upper air cylinder is in its elevated position, and as such the slidable member 16 lis likewise in its. elevated position. Such being the case, the sleeve 15 is first seated upon the chuck head of the compound container, Within the recessed portion thereof. Air being supplied to the upper end ofthe cylinder 31 forces the piston 34 down, causing the slidable member 16 to descend. In its descent the compacting member 20 which rotates continuously enters the sleeve and the head 17 engages withand closes the upper end of the same, the sleeve being thus held in position. Air is admitted into the lower cylinder 6, through port 7,; actuating the piston 9 therein and causing the piston 13 to act upon the body of lubricating compound 12 and force a charge of the coinpound up into the sleeve receptacles or groovesl. As the compound is introduced into the sleeve grooves the flutes of the compacting member 20, also become filled and being rotated, in the direction of the arrow in Fig. 4, presses or compacts the compound by a cam action, assisted by the viscosity of the compound, within the sleeve grooves, completely filling said grooves and producing a uniform and smooth filling of like density in all of the grooves, flush with the bearing surface.

' As soon as the sleeve is supplied with the compound from the container and compacter flutes, which is practically instantaneously, the air supply is cut off from the lower end of the cylinder 6, thus relieving pressure fromy the compound. At the saine time, or immediately following same, the supply of air to the upper end of the cylinder 31 is cut off and air supplied to the lower end thereof, by way of the port 32, thus causing the piston 34 to be actuated upwardly and elevate the slidable member 16, removing tlieliead 17 fronithe end of the sleeve and at the same time withdrawing the compacting member from the interior of the sleeve, the sleeve being then removed. During filling of the grooves with the compound, sufficient leakage occurs at the top of the sleeves to expel the air therefrom.

T he above description is that of one cycle of operation of the machine, the same being repeated as rapidly as the operator can supply sleeves thereto and operate the air valves.

lVhile I have not shown such, it will be readily apparent that sleeve bearings with receptacles or other forms, than that shown, such as, cavities, etc. within the bearing surfaces inav be filled with a compound, by means of this apparatus, as the compound will then enterthe receptacles by way of the flutes in the rotary member and be compacted therein by its cam action. y
